Device for holding a container

ABSTRACT

A device for holding a container is disclosed. The device includes a base configured to support the container, a retaining mechanism configured to retain the container relative to the base, and an actuator mechanism coupled to the retaining mechanism. The retaining mechanism includes a longitudinal axis and an iris moveable between an insertion position and a retaining position. A central opening formed by the iris in the insertion position has an insertion diameter greater than a retaining diameter of the central opening formed by the iris in the retaining position. The iris includes a plurality of arms arranged in a first level and a second level. User rotation of the actuator mechanism in a first direction causes the arms of the iris to move to the retaining position, and user rotation of the actuator mechanism in a second direction opposite the first direction causes the arms of the iris to move away from the retaining position towards the insertion position.

CROSS-REFERENCE TO RELATED APPLICATION

The present application is a continuation of U.S. application Ser. No. 14/690,841, filed Apr. 20, 2015, which is hereby incorporated by reference as though fully set forth herein.

BACKGROUND a. Technical Field

The disclosure relates generally to vehicle components, and more particularly, to a device for holding a container.

b. Background Art

This background description is set forth below for the purpose of providing context only. Therefore, any aspects of this background description, to the extent that it does not otherwise qualify as prior art, is neither expressly nor impliedly admitted as prior art against the instant disclosure.

There are several devices for holding containers (e.g., cupholders) for use in vehicles, such as automobiles, aircrafts, and strollers. Some devices contain spring-loaded retainers that protrude through the sidewalls of the device and that are limited in how far they can extend. Moreover, these spring mechanisms may sacrifice stability by providing only point contacts on the container toward the base of the container (rather than the top). Also, greater spring forces may have a tendency to indent or distort softer containers like Styrofoam or thin-walled plastic bottles, while lesser spring forces may offer little resistance to tipping of large containers.

Rubber or elastomer-type cupholder inserts with local, deformable extensions to secure the container may be more robust (with respect to tipping), but may have different issues. For example, because of the higher surface friction between the inserts and the container, a greater force is required to insert and remove the container from the holder. The rubber insert may tend to come out with the container, or the beverage may be spilled when the container finally dislodges from the rubber retainer (as the user may not be able to stop the momentum). The rubber inserts may also cause the user to collapse a weaker container due to the grip force required to remove it from the holder. Another issue with rubber inserts is that the lid may be inadvertently removed from the cup when the user attempts to remove the cup from the holder (i.e., the lid comes up with the user's hand). Improvements are, therefore, desired to address these challenges. Among other things, the instant disclosure seeks to improve upon the aforementioned issues.

The foregoing discussion is intended only to illustrate the present field and should not be taken as a disavowal of claim scope.

SUMMARY

In an embodiment, a device for holding a container includes a base configured to support the container, a retaining mechanism configured to retain the container relative to the base, and an actuator mechanism coupled to the retaining mechanism. The retaining mechanism includes a longitudinal axis and an iris moveable between an insertion position and a retaining position. A central opening formed by the iris in the insertion position has an insertion diameter greater than a retaining diameter of the central opening formed by the iris in the retaining position. The iris includes a plurality of arms arranged in a first level and a second level. User rotation of the actuator mechanism in a first direction causes the arms of the iris to move to the retaining position, and user rotation of the actuator mechanism in a second direction opposite the first direction causes the arms of the iris to move away from the retaining position towards the insertion position.

An advantage of the embodiments described herein is that the device can accommodate containers with various diameters as per the user's desire (i.e., device is user-adjustable). Additionally, the device closes the clearance between the container and sidewall of the device, which generates a clean appearance from above and prevents objects from getting between them. Furthermore, the devices described herein allow for greater surface contact with the container, and the contact surfaces are more uniformly distributed about the circumference of the container farther away from the base of the container. In additional embodiments, for vehicles equipped with heated and/or cooled cupholders, the devices described herein help to minimize convective heat dissipation by closing off an area around the container. These advantages aid in improving the aforementioned issues.

The foregoing and other aspects, features, details, utilities, and advantages of the present disclosure will be apparent from reading the following description and claims, and from reviewing the accompanying drawings.

DETAILED DESCRIPTION

Various embodiments are described herein to various apparatuses, systems, and/or methods. Numerous specific details are set forth to provide a thorough understanding of the overall structure, function, manufacture, and use of the embodiments as described in the specification and illustrated in the accompanying drawings. It will be understood by those skilled in the art, however, that the embodiments may be practiced without such specific details. In other instances, well-known operations, components, and elements have not been described in detail so as not to obscure the embodiments described in the specification. Those of ordinary skill in the art will understand that the embodiments described and illustrated herein are non-limiting examples, and thus it can be appreciated that the specific structural and functional details disclosed herein may be representative and do not necessarily limit the scope of the embodiments.

Reference throughout the specification to “various embodiments,” “some embodiments,” “one embodiment,” or “an embodiment,” or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in various embodiments,” “in some embodiments,” “in one embodiment,” or “in an embodiment,” or the like, in places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Thus, the particular features, structures, or characteristics illustrated or described in connection with one embodiment may be combined, in whole or in part, with the features, structures, or characteristics of one or more other embodiments without limitation given that such combination is not illogical or non-functional.

Referring now to the drawings wherein like reference numerals are used to identify identical or similar components in the various views, FIG. 1 is an isometric view of a device 20 for holding a container (not shown), wherein device 20 is in an insertion position, in accordance with an embodiment of the instant disclosure. FIG. 2 is an isometric view of device 20 in a retaining position. Device 20 may be configured to move from the insertion position to the retaining position (or any position therebetween) upon actuation by a user or system. Device 20 may also be configured to move from the retaining position to the insertion position (or any position therebetween) upon actuation by a user or system (for example and without limitation, spring-loaded rocker arms or switch activated motor).

Device 20 defines a central opening 21 configured to receive a container or beverage, opening 21 being user-adjustable. As shown in FIGS. 1-2, the size of opening 21 changes as device 20 moves to/from the insertion and retaining positions. When in the insertion position (FIG. 1), opening 21 has an insertion diameter 22; when in the retaining position (FIG. 2), opening 21′ has a retaining diameter 22′ that is less than insertion diameter 22. As such, device 20 can accommodate containers having diameters associated with the insertion position, the retaining position, or any intermediate position therebetween. Once a container or beverage is inserted into device 20, device 20 may be moved from the insertion position toward the retaining position. Depending on its size, the container or beverage may prevent device 20 from moving completely to the retaining position illustrated in FIG. 2 (i.e., the container may cause device 20 to only reach an intermediate position). Once the device 20 is in the retaining position (or an intermediate position), the container may be removed and re-inserted repeatedly without having to move the device 20 to the insertion position.

FIG. 3A is an exploded isometric view of device 20. Device 20 may comprise a retaining mechanism 23, an actuator mechanism 24, and a receptacle 26. Retaining mechanism 23 includes central opening 21 and may comprise a longitudinal axis 28 and an iris 30 movable between the insertion position (FIG. 1) and the retaining position (FIG. 2). Iris 30 may comprise a plurality of arms 32, 34 arranged in levels 36, 38. Arms 32 in level 36 may be axially disposed between actuator mechanism 24 and arms 34 of level 38. Arms 34 of level 38 may be axially disposed between arms 32 of level 36 and receptacle 26. As more particularly shown, arms 32 of level 36 may comprise a plurality of arms 32 ₁₋₃, and arms 34 of level 38 may comprise a plurality of arms 34 ₁₋₃.

A detailed explanation of the various components of device 20 follows. Thereafter, this disclosure will describe how the various components are assembled to form device 20. Lastly, this disclosure will describe how device 20 operates and how the various components thereof interact with one another.

FIGS. 4A-4C illustrate various views of receptacle 26 of device 20. Receptacle 26 may define an opening 58 and may comprise a base 60, a sidewall 62, a flange 64, pivots 54 ₁₋₃, 56 ₁₋₃ disposed on flange 64, and stops 66 ₁₋₃. Base 60 may be configured to support the container. Sidewall 62 may extend axially from base 60 and may be generally cylindrical in shape. Sidewall 62 defines a cavity 68 in which the container may reside. Flange 64 may be configured to support actuator mechanism 24 and arms 32 ₁₋₃, 34 ₁₋₃ of iris 30 (shown in FIG. 3A). Flange 64 may be disposed at a longitudinal end 70 of receptacle 26 opposite of base 60. Pivots 54 ₁₋₃, 56 ₁₋₃ may be generally cylindrical in shape and be arranged equidistantly around a circumference 65 of flange 64. Stops 66 ₁₋₃ may be configured to prevent further rotation of actuator mechanism 24. In the illustrated embodiment, stops 66 ₁₋₃ project radially outwardly from flange 64 and are arranged equidistantly around the perimeter of flange 64.

FIGS. 5A-5D illustrate various views of arm 34 ₁. In the illustrated embodiment, arms 34 _(2, 3) are identical to arm 34 ₁. In other embodiments, however, arms 34 ₁₋₃ of level 38 of iris 30 may not be identical to one another (in shape and/or function). Arm 34 ₁ is configured to pivot radially inwardly to contact the container. In the illustrated embodiment, arm 34 ₁ generally may be curved in shape and may comprise a top surface 72 ₁, an inner edge 74 ₁ configured to contact the container, an outer edge 76 ₁ opposite of inner edge 74 ₁, an aperture 78 ₁, a slot 80 ₁ extending radially inwardly from outer edge 76 ₁, and an arm guide 82 ₁. Slot 80 ₁ may be disposed generally between a midpoint 84 ₁ of arm 34 ₁ and a longitudinal end 86 ₁ of arm 34 ₁. Arm guide 82 ₁ may have longitudinal ends 88 ₁, 88 ₁′. Arm guide 82 ₁ may also be a through hole and may be disposed between slot 80 ₁ and a longitudinal end 90 ₁ of arm 34 ₁. Arm guide 82 ₁ may also be curved. One of ordinary skill in the art will understand that the dimensions, curvature, and positioning of arm guides 82 ₁₋₃ may have certain dependencies, namely, the size of arms 32 ₁₋₃, 34 ₁₋₃, the desired diameters for the retaining and insertion positions, and the effort needed from the user or system to actuate the device, among other things. Moreover, although arm guides 82 ₁₋₃ are illustrated as being identical in shape and size, arm guides may be of different shapes and sizes, depending on the actuation desired.

FIGS. 6A-6D illustrate various views of arm 32 ₁. In the illustrated embodiment, arms 32 _(2,3) are identical to arm 32 ₁. In other embodiments, however, arms 32 ₁₋₃ of level 36 of iris 30 may not be identical to one another (in shape and/or function). Arm 32 ₁ is configured to pivot radially inwardly to contact the container. In the illustrated embodiment, arm 32 ₁ generally may be curved in shape and may comprise a top surface 96 ₁, a bottom surface 98 ₁, an inner edge 100 ₁ configured to contact the container, an aperture 102 ₁, an actuating cam 104 ₁ projecting axially upwardly from top surface 96 ₁, and an arm cam 106 ₁ projecting axially downwardly from bottom surface 98 ₁. Actuating cam 104 ₁, which may be cylindrical in shape, may be configured to engage with actuator mechanism 24 (shown in FIG. 3A). Actuating cam 104 ₁ may be disposed at a longitudinal end 108 ₁ of arm 32 ₁, and aperture 102 ₁ may be disposed at a longitudinal end 110 ₁ of arm 32 ₁, opposite of longitudinal end 108 ₁. Arm cam 106 ₁ may be generally cylindrical in shape and may be configured to engage with arm 34 ₁ below arm 32 ₁. Arm cam 106 ₁ may be disposed generally between a midpoint 116 ₁ of arm 32 ₁ and longitudinal end 110 ₁ of arm 32 ₁.

FIG. 7 is a bottom isometric view of actuator mechanism 24. Actuator mechanism 24 is configured to allow a user or system to move arms 32 ₁₋₃, 34 ₁₋₃ so as to assume one of the insertion position and the retaining position (or an intermediate position therebetween). In the illustrated embodiment, actuator mechanism 24 is a ring 136. Ring 136 may comprise an outer wall 138, slots 140 ₁₋₃ disposed therein, attachment clips 142 ₁₋₃, and actuating guides 144 ₁₋₃ formed in a bottom surface 146 of ring 136. Slots 140 ₁₋₃ may be arranged equidistantly around outer wall 138. Attachment clips 142 ₁₋₃ may be configured to facilitate coupling of ring 136 to receptacle 26. Attachment clips 142 ₁₋₃ may each have a projection 148 ₁₋₃ that projects radially inwardly. Actuating guides 144 ₁₋₃ are configured to engage with arms 32 ₁₋₃, respectively. Actuating guides 144 ₁₋₃ may each have longitudinal ends 149 ₁₋₃, 149 ₁₋₃′. In the illustrated embodiment, actuating guides 144 ₁₋₃ are curved and are arranged circumferentially equidistantly on bottom surface 146 of ring 136. In an embodiment, actuating guides 144 ₁₋₃ may have a width 150 of four millimeters, and longitudinal ends 149 ₁₋₃, 149 ₁₋₃′ may have an inner radius of curvature 152 a of thirty-four millimeters and an outer radius 152 b of curvature of thirty-eight millimeters. In one embodiment, a gap 152 c between longitudinal end 149 ₁₋₃′ and an inner edge of ring 136 may be two millimeters. Although specific dimensions are mentioned, one of ordinary skill in the art will understand that the dimensions, curvature, and positioning of actuating guides 144 ₁₋₃ may have certain dependencies, namely, the size of arms 32 ₁₋₃, the desired diameters for the retaining and insertion positions, and the effort needed from the user or system to actuate the device, among other things. Moreover, although actuating guides 144 ₁₋₃ are illustrated as being identical in shape and size, actuating guides may be of different shapes and sizes, depending on the actuation desired.

A description of how the components of device 20 are assembled is now provided. FIG. 8 illustrates device 20 in various stages of assembly. Flange 64 of receptacle 26 may serve as the base for arms 32 ₁₋₃, 34 ₁₋₃ and for ring 136. Each pivot 54 ₁₋₃, 56 ₁₋₃ on flange 64 may extend through a corresponding arm 32 ₁₋₃, 34 ₁₋₃, respectively. In the illustrated embodiment, there are six pivots 54 ₁₋₃, 56 ₁₋₃, one for each arm 32 ₁₋₃, 34 ₁₋₃ of iris 30, respectively. In other embodiments, however, one pivot may extend through more than one arm (and serve as a pivot for those arms). Pivots 54 ₁₋₃ may have a height 147 measured from top surface 70 of flange 64, and pivots 56 ₁₋₃ may have a height 148 measured from top surface 70 of flange 64. In the illustrated embodiment, height 147 of pivots 54 ₁₋₃ is greater than height 148 of pivots 56 ₁₋₃ since pivots 54 ₁₋₃ extend farther up to arms 32 ₁₋₃. Also, in the illustrated embodiment, pivots 54 ₁₋₃, 56 ₁₋₃ all lie on a centered circumference 65 of flange 64, which is midway between the inner and outer diameters of flange 64. In other embodiments, however, pivots 54 ₁₋₃, 56 ₁₋₃ may be disposed at various points on flange 64, and may not lie on the same circumference.

Arms 34 ₁₋₃ are coupled to flange 64 via insertion of pivots 56 ₁₋₃ through apertures 78 ₁₋₃ of arms 34 ₁₋₃, respectively, and insertion of pivots 54 _(1,2,3) through slots 80 _(3,1,2), respectively. Slots 80 ₁₋₃ may be configured to permit pivots 54 ₁₋₃ to extend through arms 34 ₁₋₃ to arms 32 ₁₋₃ but may also be configured to aid in guiding arms 34 ₁₋₃ upon actuation of ring 136. Once coupled, arms 34 ₁₋₃ together extend circumferentially around a substantial portion of flange 64, leaving only gaps 151 ₁₋₃. Arms 32 ₁₋₃ are coupled to flange 64 and to arms 34 ₁₋₃ via insertion of pivots 54 ₁₋₃ through apertures 102 ₁₋₃ of arms 32 ₁₋₃, respectively, and insertion of arm cams 106 ₁₋₃ of arms 32 ₁₋₃ (FIGS. 6C-6D) in arm guides 82 ₁₋₃ of arms 34 ₁₋₃, respectively. In the illustrated embodiment, there are three arm guides 82 ₁₋₃, and each arm guide 82 ₁₋₃ corresponds to an arm cam 106 ₁₋₃ of arm 32 ₁₋₃ (FIGS. 6C-6D), respectively. Once coupled, arms 32 ₁₋₃ together overlap a majority of the top surfaces of arms 34 ₁₋₃ and also gaps 151 ₁₋₃. Also, in the illustrated embodiment, the longitudinal ends of arms 32 ₁₋₃ are offset from the longitudinal ends of arms 34 ₁₋₃ such that midpoints 116 ₁₋₃ of arms 32 ₁₋₃ are disposed over gaps 151 ₁₋₃. The size and number of gaps can vary; in some embodiments, there may be little to no gaps between the arms.

Still referring to FIG. 8, ring 136 is coupled to receptacle 26 by aligning actuating cams 104 ₁₋₃ of arms 32 ₁₋₃ with actuating guides 144 ₁₋₃ (FIG. 7) of ring 136, respectively, and also by aligning stops 66 ₁₋₃ of receptacle 26 with slots 140 ₁₋₃ of ring 136, respectively. In the illustrated embodiment, there are three actuating guides 144 ₁₋₃ (FIG. 7), and each actuating guide 144 ₁₋₃ corresponds to an actuating cam 104 ₁₋₃ of arm 32 ₁₋₃, respectively. A tapered or radial lead-in may be provided on either actuating guides 144 ₁₋₃ of ring 136, actuating cams 104 ₁₋₃ of arms 32 ₁₋₃, or both to allow assembly with minor misalignment. Ring 136 is also coupled to receptacle 26 via attachment clips 142 ₁₋₃ which are integral with ring 136. Attachment clips 142 ₁₋₃ will now be described in detail.

FIG. 9 is a partial, enlarged, cross-sectional view of a portion of device 20. As ring 136 is pushed over flange 64, clips 142 ₁₋₃ bow radially outwardly and then snap radially inwardly such that surfaces 152 ₁₋₃ of projections 142 ₁₋₃ engage a lip 153 of flange 64. Once attached, outer wall 138 and bottom surface 146 of ring 136 and top surface 70 of flange 64 define a cavity 154 in which arms 32 ₁₋₃, 34 ₁₋₃ of iris 30 may reside when in the insertion position. Ring 136 may be decoupled from flange 64 by manually bowing clips 142 ₁₋₃ radially outwardly and removing. In the illustrated embodiment, there are three attachment clips 142 ₁₋₃; however, more or less clips may be used.

With continual reference to FIG. 8, a description of how device 20 operates will now be provided. In one embodiment, rotation of ring 136 in a first direction 155 causes arms 32 ₁₋₃, 34 ₁₋₃ of iris 30 to close down the size of central opening 21 (i.e., toward the retaining position) (as shown in FIG. 2). Additionally, rotation of ring 136 in a second opposite direction 156 causes arms 32 ₁₋₃, 34 ₁₋₃ of iris 30 to open up to increase the size of central opening 21 (i.e., toward the insertion position). In another embodiment, directions 155, 156 are reversed. Ring 136 may be manually rotated by the user or, alternatively, may be automated using mechanical devices (e.g., spring-loaded rocker arms 162—see device 20′″ in FIG. 3D) or electro-mechanical devices 164—see device 20′ in FIG. 3B (switch activated motor 166—see device 20″ in FIG. 3C). Although actuator mechanism 24 is illustrated as comprising ring 136, actuator mechanism 24 can take on other forms other than ring 136 (i.e., pivoting of arms 32 ₁₋₃, 34 ₁₋₃ can be actuated by other means).

As ring 136 rotates, actuating guides 144 ₁₋₃ disposed on bottom surface 146 of ring 136 (FIG. 7) correspondingly rotate relative to axis 28. As such, the movement of actuating guides 144 ₁₋₃ of ring 136 causes actuating cams 104 ₁₋₃ of arms 32 ₁₋₃ to move and travel within actuating guides 144 ₁₋₃, respectively. Such travel causes arms 32 ₁₋₃ to pivot relative to their respective pivots 54 ₁₋₃.

Still referring to FIG. 8, as a result of such pivoting of arms 32 ₁₋₃, arm cams 106 ₁₋₃ on bottom surface 98 ₁₋₃ of arms 32 ₁₋₃ (FIGS. 6C-6D) move with their respective pivoting arm 32 ₁₋₃ and travel within arm guides 82 ₁₋₃ of arms 34 ₁₋₃, respectively. Such travel causes arms 34 ₁₋₃ to pivot relative to their respective pivots 56 ₁₋₃. In addition, while arms 34 ₁₋₃ pivot radially inwardly or outwardly, pivots 54 ₁₋₃ for the adjacent arm 32 ₁₋₃ (which extend through apertures 102 ₁₋₃ of arms 32 ₁₋₃) travel within slots 80 ₁₋₃ of arms 34 ₁₋₃. For example, in the illustrated embodiment, pivot 54 ₃ extends through aperture 102 ₃ of arm 32 ₃ and travels within slot 80 ₂ of arm 34 ₂. Such travel of pivots 54 ₁₋₃ within slots 80 ₁₋₃ may aid in guiding the pivotal movement of arms 34 ₁₋₃. Dissimilar materials with different coefficients of thermal expansion may be used on interfacing elements to avoid loss of clearance between guides or slots and cams or pivots over the operating temperature range.

Upon moving in either direction 155 or 156, ring 136 will come to a stop through the interaction of stops 66 ₁₋₃ of flange 64 with slots 140 ₁₋₃ of ring. Stops 66 ₁₋₃ travel within slots 140 ₁₋₃ until stops 66 ₁₋₃ contact the respective endwalls of slots 140 ₁₋₃. In the illustrated embodiment, ring 136 comprises three slots 140 ₁₋₃; however, one of ordinary skill in the art will understand that ring 136 may comprise less or more than three stops 66 ₁₋₃. Furthermore, the ratio of stops to slots may not be one-to-one. In addition, stops 66 ₁₋₃ with or without slots 140 ₁₋₃ may instead be disposed internally of outer wall 138 of ring 136.

In operation, arms 32 ₁₋₃, 34 ₁₋₃ move synchronously to close the clearance between the container and sidewall 62 of receptacle 26 and/or inner edge of ring 136, which generates a clean appearance from above and prevents objects from falling therebetween.

In the illustrated embodiment, flange 64 is stationary relative to ring 136 and iris 30. As such, pivots 54 ₁₋₃, 56 ₁₋₃ projecting axially from top surface 70 of flange 64 are also stationary relative to iris 30. Although flange 64 is illustrated as being integral with receptacle 26, one of ordinary skill in the art will understand that flange 64 may be a component separate from receptacle 26 and that the device 20 may be provided without the receptacle 26 and/or base 60 and be assembled into a separate cup holder as desired.

In the insertion position, actuating cams 104 ₁₋₃ of arms 32 ₁₋₃ are disposed at longitudinal ends 149 ₁₋₃ of actuating guides 144 ₁₋₃, respectively, in ring 136 (see FIG. 7 for longitudinal end 149 ₁). In the retaining position, actuating cams 104 ₁₋₃ are disposed at longitudinal ends 149 ₁₋₃′ of actuating guides 144 ₁₋₃ (see FIG. 7 for longitudinal end 149 ₁′). Although longitudinal ends 149 ₁₋₃, 149 ₁₋₃′ correspond to the positions of actuating cams 104 ₁₋₃ when device 20 is in the insertion and retaining positions, respectively, other positions within actuating guides 144 ₁₋₃ may correspond to the insertion and retaining positions. Furthermore, although actuating guides 144 ₁₋₃ are illustrated as being formed in ring 136 and actuating cams 104 ₁₋₃ are illustrated as being disposed on arms 32 ₁₋₃, one of ordinary skill in the art will understand that this arrangement may be reversed (i.e., actuating guides 144 ₁₋₃ may be formed in arms 32 ₁₋₃, and actuating cams 104 ₁₋₃ may be disposed on ring 136).

With reference to FIG. 5B, in the insertion position, arm cam 106 ₁ of arm 32 ₁ is disposed at longitudinal end 88 ₁ of arm guide 82 ₁ of arm 34 ₁; in the retaining position, arm cam 106 ₁ is disposed at longitudinal end 88 ₁′ of arm guide 82 ₁ (arm cam 106 ₁ shown in FIGS. 6C and 6D). In the illustrated embodiment, arm cams 106 _(2,3) are similarly positioned in arm guides 82 _(2,3) (when in the insertion and retaining positions). Although arm guides 82 ₁₋₃ are illustrated as being formed in arms 34 ₁₋₃, respectively, and arm cams 106 ₁₋₃ are illustrated as being disposed on arms 32 ₁₋₃, respectively, one of ordinary skill in the art will understand that this arrangement may be reversed (i.e., arm guides 82 ₁₋₃ may be formed in arms 32 ₁₋₃, and arm cams 106 ₁ may be disposed on arm 34 ₁₋₃).

In the illustrated embodiment, arms 32 ₁₋₃ of level 36 and arms 34 ₁₋₃ of level 38 define openings 21, 21′ (and thus diameters 22, 22′, shown in FIGS. 1 and 2), such that a substantial portion of each arm 32 ₁₋₃, 34 ₁₋₃ contacts the container or beverage. One of ordinary skill in the art will understand, however, that in other embodiments, either plurality of arms 32 ₁₋₃ or plurality of arms 34 ₁₋₃ may contact the container and define opening 21′ (e.g., arms 32 ₁₋₃ may actuate movement of arms 34 ₁₋₃, respectively, but not contact the container). Furthermore, in the illustrated embodiment, the rotation of ring 136 actuates the movement of the arms 32 ₁₋₃ of level 36, respectively, and arms 32 ₁₋₃ correspondingly actuate movement of arms 34 ₁₋₃ of level 38, respectively. One of ordinary skill in the art will understand, however, that the actuation flow may be reversed (i.e., ring 136 may actuate movement of arms 34 ₁₋₃, and arms 34 ₁₋₃ may actuate movement of arms 32 ₁₋₃).

Furthermore, although the illustrated embodiment shows actuator mechanism 24 as being ring 40, which is in the topmost position (relative to iris 30), actuator mechanism 24 may be in the bottom-most position (relative to iris 30). For example and without limitation, actuator mechanism 24 may be receptacle 26 (or a portion thereof), and pivots 54 ₁₋₃, 56 ₁₋₃ may instead project axially downwardly from ring 40, which may be fixed relative to iris 30.

Although the illustrated embodiment generally illustrates two pairs of cams and guides for each pair of upper and lower arms (one pair associated with ring 136 and arm 32 ₁, and another pair associated with arm 32 ₁ and arm 34 ₁), one of ordinary skill in the art will understand that more pairs of cams and guides may be utilized among the various components to facilitate the opening and closing of iris 30. Furthermore, other mechanical components may be utilized (other than cams and guides) to produce the same actuation flow from an actuator mechanism 24 to a two-level iris 30. Additionally, although iris 30 is illustrated as having two levels, more levels may be used.

FIG. 10 is a simplified, partial, cross-sectional view of device 20 in the insertion position. As illustrated, arms 32 ₁₋₃ may travel in a plane 156 parallel to a base plane 158, which is generally horizontal, and arms 34 ₁₋₃ may travel in a plane 160 parallel to plane 156 (and to base plane 158). In other embodiments, arms 32 ₁₋₃ and arms 34 ₁₋₃ may travel in planes not parallel to each other or to base plane 158. For example and without limitation, planes 156, 160 may be at an angle relative to base plane 158.

The foregoing numerous embodiment solve one or more problems known in the art.
